I don't think a dedicated parser for the init expression is a good direction.
It implements another text instruction parser.
The extended-const proposal adds `i32.add`/`sub`/`mul`, `global.get` etc. with
a stack discipline, and we already have the instruction parser/matcher for
function bodies that knows all of these. Can we parse the const expr through
the normal `parseInstruction` -> `MCInst` path and convert the resulting
`MCInst`s to a `WasmInitExpr`? Otherwise this will need to grow into a second
mini assembler.
